An improved method of competitively excluding pathogens capable of intestinal colonization, such as Salmonella or Cambylobacter, from a digestive tract of a bird comprises administration in ovo to a fertile bird egg of a competitive exclusion (CE) culture essentially free from bacteria which abundantly form gas such as Clostridium species. The CE culture may be any CE culture essentially free from abundant gas forming bacteria which culture is derived from a digestive tract of a bird free from pathogens. The CE culture may be administered either into the air cell or the amnion of a fertile bird egg, preferably into the amnion.

Ovo administration of a competitive exclusion culture

This invention provides a composition useful in the treatment or prophylaxis of disturbances in the normal intestinal bacteria flora in poultry. The composition is intended to be administered as an aqueous mixture and it contains anaerobic bacteria of intestinal origin and an agent, preferably cysteine, which decreases the toxic effect of the oxygen dissolved in the water, and preferably also a substantially neutral buffer.
